An efficient solventless one-pot procedure for the synthesis of imidazolium-based ionic liquid under microwave irradiation is described in which 1-methylimidazole was modified by organosilane (3-chloropropyl triethoxysilane). This ionic liquid 1-methyl-3-[(triethoxysilyl)propyl]imidazolium chloride (TMICl) is immobilized on Mechanically activated Fly Ash (MFA) by co-condensation method to d...

THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: (R,R)-2,4-bis-(4-hydroxy-phen-yl)-N,N'-dimethyl-3-oxapentane-1,5-diammonium bis-(hydrogen sulfate)], C(18)H(26)N(2)O(3) (2+)·2HSO(4) (-), contains one half-cation and one hydrogen sulfate anion. The cation has crystallographically imposed twofold symmetry with the rotation axis passing through the central ether O atom. Hydrogen bonds b...

The title compound, (C(3)H(5)N(2))(4)[As(6)CuMo(6)O(30)], is made up of a centrosymmetric anionic cluster and four imidazolium cations. In the cluster, the central Cu(II) atom is six-coordinated and lies on an inversion center. Adjacent clusters are linked via N-H⋯O hydrogen bonds between the imidazole cations and polyoxidoanions into a three-dimensional supra-molecular architecture.

The application of sulfur isotope (dS) values of sulfate in groundwater provided the information necessary to evaluate the source, transport and fate of battery acid and associated contaminants at the Gulf Coast Recycling (GCR) facility. The chemical and isotopic composition of groundwater beneath the (GCR) property, a battery recycling facility in east Tampa, Florida, varies more than expected...

The crystal structure of the title compound, [Fe(C(5)H(5))(C(10)H(12)N(2))]PF(6), consists of a ferrocene-1-methyl-(3-methyl-imidazolium) cation and a hexa-fluorido-phosphate anion. The ferrocenyl rings are skewed by 6.7 (4)° from the ideal eclipsed conformation. The inter-planar angle between the plane of the substituted cyclo-penta-dienyl ring and that of the imidazole ring is 89.9 (4)°. The ...

Desulfovitio d&dfUTiCam is an obligately anaerobic organism that can bc grown heterotrophically with sulfate and an organic electron donor or autotrophically with sulfate, hydrogen, and CO* (1). The presence of sulfate is obligatory for growth both with hydrogen and organic electron donors, except in the case of pyruvate (2). During growth, large amounts of sulfide are produced from the sulfate...

The title compound, eprosartan mesylate {systematic name: 2-butyl-1-(4-carb-oxy-benz-yl)-5-[(E)-2-carb-oxy-3-(thio-phen-2-yl)prop-1-en-yl]-1H-imidazol-3-ium methane-sulfonate}, C(23)H(25)N(2)O(4)S(+)·CH(3)O(3)S(-), one of the angiotensin II-receptor antagonists, is effective in regulating hypertension, induced or exacerbated by angiotensin II, and in the treatment of congestive heart failure, r...

In the title compound, C(15)H(17)N(2) (+)·Br(-), the cyclo-butene and benzene rings are coplanar. The dihedral angle between the benzene and imidazolium rings is 21.2 (3)°. In the crystal structure, the C(15)H(17)N(2) (+) and Br(-) ions are linked into a zigzag chain along the b axis by C-H⋯Br hydrogen bonds, and weak C-H⋯π inter-actions involving the benzene ring of a screw-related cation.

Hyaluronic acid (HA) has a number of potential biomedical applications in drug delivery and tissue engineering. For these applications, a prerequisite is to understand the characteristic of HA films directly immobilized to solid substrates. Here, we demonstrate that high molecular weight HA can be directly immobilized onto hydrophilic substrates without any chemical manipulation, allowing for t...

In the crystal structure of the title compound, C(20)H(39)N(2) (+)·Br(-)·H(2)O, the 1-hexa-decyl-3-methyl-imidazolium cations are stacked along the b axis, forming channels parallel to [100] which are occupied by the bromide anions and water mol-ecules. The crystal is stabilized by O-H⋯Br, C-H⋯O and C-H⋯Br hydrogen-bonding inter-actions, generating a two-dimensional network.
